压缩包程序一共4个，一个主程序，是绘制天线的均匀直线阵的极坐标图和三维立体图，程序附有中文解释。另外3个程序是，均匀直线阵的工程应用：边射阵、普通端射阵、强方向性端射阵。(Procedures for a total package 4, a main program, is the preparation of the uniform linear array antenna of the polar map and three-dimensional map, with the Chinese to explain the procedure. Other three procedures, uniform linear array of engineering applications: Front side shot, the general array endfire, strong directional endfire array.)

ex9_12 二相编码信号的脉压处理，13位巴克码用于雷达的二相编码脉冲压缩中，由于巴克码具有好的自相关函数，所以其脉压结果很好(BPSK ex9_12 pulse pressure signal processing, 13 Barker Code for the two-phase coded radar pulse compression, as a result of Barker codes have good auto-correlation function, so its a very good pulse pressure results)
